M5-0.8 x 3 Cup Point Alloy Steel Metric Socket Set Screw is a headless internal-hex set screw for locking collars, hubs, and controls on metric shafts.

Metric shaft collars, locating rings, and bearing retainers can use this screw when the design accepts cup-point marking. Because this is a set screw, selection should focus on point style, socket size, thread engagement, and the installation conditions rather than tensile terminology. Review the metric diameter, length, cup diameter, and hex key together before substitution.

Cold Headers supports imported equipment rebuilds where the replacement screw must match the original metric callout.
